If Djokovic wants a current example of a player who makes parenthood on the pro tennis circuit work, he need look no further than Roger Federer.

Federer, father of two sets of twins, is enjoying a career resurgence that has many tipping him to be lifting an 18th Grand Slam trophy in two weeks.Federer said he didn`t know if he had any specific advice to offer Djokovic, except to enjoy it all.

"I think he must be quite excited about what`s going to happen soon," Federer said. "And with the wedding and everything -- he`s going through a great spell at the moment, with winning Wimbledon on top of it.

"But I think he`s got to figure it out himself really. But the good thing, he sees me with four (children), so with one it should be a piece of cake."

Overall Djokovic believes happiness in his personal life can translate into better tennis, even as family gains importance.

He`s determined to make the most of his talent and fitness while he can, and eager to add a second title at a tournament where he has finished runner-up four times, in 2007, 2010, 2012 and 2013.

"Especially at this stage of my career, where I feel like now is the time that I`m at my peak physical strength, I want to use this time of my career as much as I can to win as many matches as possible," he said.

"This is the last Grand Slam of the year, and this is where you want to play your best."
